How much water in a 10 gallon pot?

Seems like the probe recommended above would take all these variables into account?

They tell you whether it is wet or dry! And that’s all you really need to know! Easy to use!

Soil probes are great and you'll learn a lot from using one if you haven't, no matter how long you've been an aggie.

BTW watering is a little different when you have a little plant in a big container. They should be watered similarly to being in ground... You water at the drip line but you also have to maintain overall soil moisture minimums throughout the medium to ensure good microbe health. One of the reasons to put a plant in a proper size container is to avoid the extra fuss associated with properly watering it.

I’ll be picking one of these very quickly. I didn’t know if they were trustworthy or not, but if Oldchucky says it’s good, I’m buying it. I probably wasn’t going to be able to lift this pot too much longer anyway. And hard numbers satisfy my OCD a lot more than trying to guess something I have no clue about.

Too late I got the last one

Yeah, that’s fine! But the most important part is how often you do it! That’s where it can get a little tricky! But nothing insurmountable! It gets easier with experience! Like all of this weed growing stuff! and from what I’ve seen most people do it too often!

Yeah, I'm a mod for another community that focuses on new growers, and over-watering is the number one issue we see, (followed closely by over-lighting and over-feeding. ) With amended peat-based soils like HF and OF, watering slowly to runoff, only when the pots are very light, is a pretty good starting point.

There was an old episode of Home Improvement where Tim was tasked with making Thanksgiving dinner so he read the instructions calling for 350 degrees for four hours and said hey I'll just do 700 for two hours... As new growers we are thinking like that, and that's why things often go horribly wrong.

This is a 10-12 week auto. A place or two I was reading said autos don’t take too well to multiple transplants. I think it was over on Grow Weed Easy, which is really the only other place I get my info. Would keeping it in a smaller pot and then up potting when necessary be worth the easier/better watering practice?

You might be in a little bit larger pot than necessary, but there’s no reason you can’t water them properly! Pay attention to that drip line stuff that ninja was talking about! There is a reason that plants grow from the top in a Christmas tree like form most of the time! The canopy catches the water, channels it to the outside of the lower canopy and drops it on the ground at what is called the drip line! Which just happens to be a little bit wider than where the roots are at that point! Thus encouraging the roots to expand outward Following the canopy! There is definitely a method to her madness! So adjusting your watering to the drip line is a good idea! There’s no way that plant will fill a 10 gallon pot! So you have to make adjustments!

Everybody’s 10 gallon pot in different climates with different soil mixes is going to dry out at a different rate! And as the plant gets bigger, it will contribute more and more to drying it out! There is no one-size-fits-all! With one of these you can get an idea of what is going on in every inch of the pot! Weather from the top, through the side, whatever! Guess work is no Bueno! Probably the most indispensable tool I have! Long probe. $14.99 plus tax! And I don’t PH anything! But would guess that 7.7 is OK!View attachment 2446903

Product acquired! Now, how far into “dry” do you let it get before you water.

I let it get to the top of the red! And then Water, good! In a pot of that size, the roots underneath will be almost a mirror image of the plant that is growing up top! In terms of depth and width of the canopy! So you wanna take your reading within that zone! You won’t hurt the roots! It is the tip that measures a moisture! A lot of times the outside of the pot will dry faster than the middle! And the bottom, half of the pot will dry slower than the top half! Just kind of logical! So if the plant is 10 inches tall, you want to take your reading around 10 inches deep! If you take your reading at 13 or 14 inches it still may be soaking wet down there and can throw you off! Probe around with it! It’s kind of like mapping out the pot in your mind! If you water the entire pot, the bottom will never dry out! And I don’t think roots like growing into soaking wet, medium much more than they do dry medium! So to get the bottom to dry out, you can stick it in through the side of the bag at a point that registers may be halfway! And then only Water till the needle starts moving! That way you’re not continually soaking the bottom of the pot! This is probably very confusing And auto‘s probably aren’t going to come close to filling that pot up! But photos will! Just to start stick it in to where you think the roots are and if it’s getting dry water! But give it a good dry! It’s kind of like custom watering! if you get a chance, search, new simplified way to Water! By comfortably, numb! It can probably do a better job of explaining it than my gibberish!

Thread read. I love this technique. Takes the need to actually learn to water by experience and chucks it out the window, which is perfect for a noob like me. Thanks!

I use 5 ga. Fabric pots with fox farm happy frog soil, ewc and some extra perlite. In veg I’ll water with about a gallon. Maybe 16oz less than a full gallon. Towards mid-late flower it’s usually 32oz. Less than a full gallon. But I’m watering more often than veg. For a 10 gallon. I would double it. So close to 2 gallons of water. My fool proof way of figuring out how often to water is, let the pot dry till the plant wilts. Slowly water till it starts dripping from the center of the pot. Now count your days till the plant wilts again. And water one day sooner. As the plant gets bigger you will have to water more frequently. Hope this helps.

Quick question: in a 10 gallon pot after a full dry back about how much water should be given to fully water the plant? I really don’t have any way to collect runoff, so I’m hoping someone experienced can give me a guideline. I gave her about 5-6 quarts yesterday and she seemed pretty happy until late this afternoon when she got a little droopy. The soil seems slightly moist, but not completely wet or dry. So I’m not sure if I added enough yesterday.
This is my first soil grow.

I wouldn't get too hung up on how much to water on any given watering. Last year I used 15 gallon pots. I gave them 2.5 Gallons each at each feeding. You're watering until run off. You can't over water in one watering, but you can underwater. The important thing is not to water them too frequently. For 10 Gallons, I would give them a minimum of a gallon; maybe no more than 2. Just make sure you get some run off. Looks like you have cloth pots. What I did was punch a few small holes near the bottom of each so I could see if water was running off. Just my two cents. No expert here, but this worked for me.
